Table 2: Pb stable isotope ratios for the total anthropogenic component (TAC) according to the mixture model proposed by Ferrand et al. [35] for the different fractions studied in core SS10T01 (N=10). TAC values for an intertidal core (SSPMA) recovered in the study are also shown for allowing comparison [10]. Isotopic ratios for natural sediments typical of the granitic watershed of the San Simón Bay and for a gypsum (P3) and a ceramic glaze (P4) samples collected in the waste channel of the ceramic factory located in the study area are also indicated [4].
